Cervical joint position error (JPE) has been used as a measure of cervical afferent input to detect disturbances in sensori-motor control as a possible contributor to a neck pain syndrome. This study aimed to investigate the relationship between cervical JPE, balance and eye movement control. It was of particular interest whether assessment of cervical JPE alone was sufficient to signal the presence of disturbances in the two other tests. One hundred subjects with persistent whiplash-associated disorders (WADs) and 40 healthy controls subjects were assessed on measures of cervical JPE, standing balance and the smooth pursuit neck torsion test (SPNT). The results indicated that over all subjects, significant but weak-to-moderate correlations existed between all comfortable stance balance tests and both the SPNT and rotation cervical JPE tests. A weak correlation was found between the SPNT and right rotation cervical JPE. An abnormal rotation cervical JPE score had a high positive prediction value (88%) but low sensitivity (60%) and specificity (54%) to determine abnormality in balance and or SPNT test. The results suggest that in patients with persistent WAD, it is not sufficient to measure JPE alone. All three measures are required to identify disturbances in the postural control system.
颈椎关节位置误差（JPE）已被用作衡量颈椎传入输入的指标，以检测感觉运动控制中的紊乱，这可能是颈部疼痛综合征的一个促成因素。本研究旨在探讨颈椎JPE、平衡和眼球运动控制之间的关系。特别令人感兴趣的是，仅评估颈椎JPE是否足以表明在其他两项测试中存在紊乱。对100名患有持续性挥鞭样相关疾病（WAD）的受试者和40名健康对照受试者进行了颈椎JPE、站立平衡和平滑跟踪颈部扭转试验（SPNT）的测量。结果表明，在所有受试者中，所有舒适站姿平衡测试与SPNT和旋转颈椎JPE测试之间均存在显著但弱至中等程度的相关性。在SPNT和右旋转颈椎JPE之间发现了微弱的相关性。异常的旋转颈椎JPE评分对确定平衡和/或SPNT测试中的异常具有较高的阳性预测值（88%），但敏感性（60%）和特异性（54%）较低。结果表明，在患有持续性WAD的患者中，仅测量JPE是不够的。需要所有这三项测量来识别姿势控制系统中的紊乱。
